Embedded Base64 image isn’t rendered

[WinWurm]

Hi, i have faced with rendering issues with some svg files. The embedded png image doesn’t rendered
Here is the file

File structure look like this

<svg width="80" height="80" viewBox="0 0 80 80" fill="none" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink">
    <rect width="80" height="80" rx="8" fill="white"/>
    <rect x="2" y="10.7491" width="76" height="58.5017" fill="url(#pattern0_373_2050)"/>
    <defs>
        <pattern id="pattern0_373_2050" patternContentUnits="objectBoundingBox" width="1" height="1">
            <use xlink:href="#image0_373_2050" transform="scale(0.00171821 0.00223214)"/>
        </pattern>
        <image id="image0_373_2050" width="582" height="448" xlink:href="data:image/png;base64,<image data>"/>
    </defs>
</svg>

if i change file structure to more simple form (remove defs section) all renders correct

<svg width="80" height="80" viewBox="0 0 80 80" fill="none" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink">
    <rect width="80" height="80" rx="8" fill="white"/>
    <image  x="2" y="10.7491" width="76" height="58.5017" xlink:href="data:image/png;base64,<image data>"/>
</svg>

I don’t know exactly, but it’s looks like the issue occurs because image UIGraphicsImageRenderer initiated with svg size (defined at file beginning) and embedded image renders in more bigger rect width="582" height="448" by using CGRenderer.draw(image: CGImage, in rect: CGRect) and only after rendering its scaling

Thanks for reporting this, it appears to be an issue when using <pattern> and how it calculates the projected coordinates.
I will investigate further but sidestepping pattern and directly using <image> is best for now 👍🏻
